FAQs - Ball Valves
What is a ball valve?
A ball valve is a type of quarter-turn valve with a hollow, pivoting ball inside. It controls flow by opening and closing the ball through a handle or lever.
What are the applications of ball valves?
Ball valves are widely used in various industries for shut-off and flow control in water systems, oil and gas pipelines, HVAC, chemical processing, and more.

| Ball Valves frequently asked questions |
How do ball valves work?
When the handle is turned, the ball rotates 90 degrees, aligning or blocking the flow passage. It's a quick and efficient on-off control mechanism.
What are the advantages of ball valves?
Ball valves offer reliable sealing, low maintenance, fast operation, and suitability for high-pressure and high-temperature applications.
Are ball valves suitable for throttling?
While they can throttle flow, Ball Valves are better for on-off control. They may experience cavitation and erosion if used for extensive throttling.
How do you choose the right ball valve?
Consider factors like valve size, material, pressure rating, temperature range, flow requirements, and the specific application needs.
What is the difference between a floating ball and a trunnion-mounted ball valve?
Floating Ball Valves have the ball attached to the stem, while trunnion-mounted Ball Valves have additional support for larger sizes and higher pressure.
Can Ball Valves be automated?
Yes, Ball Valves can be fitted with actuators to enable remote operation and integration into automated systems.
What is the typical life expectancy of a Ball Valve?
With proper maintenance and usage, Ball Valves can last for many years, even in demanding environments.
Are there different types of Ball Valves?
Yes, there are full-port and reduced-port ball valves, as well as multi-port Ball Valves for more complex flow configurations.
What maintenance do Ball Valves require?
Regular inspection, cleaning, and lubrication are essential for optimal performance and to prevent leaks or corrosion.
Can Ball Valves handle corrosive fluids?
Yes, depending on the material used, Ball Valves can handle corrosive fluids in various industries, including chemical processing.
